Hi, where can I find this function doom-modeline-refresh-frame? I can only find doom-modeline-refresh-bars in doom-modeline.
I found it. I'll test it later.
FYI, it's not defined in 26.1+ and no docstring. The issue is weird.
Does it exist in emacs 26.1? I see your emacs is emacs 26.1 and the function is not defined in 26.1.
Yes, the cods check if after-focus-change-function exists and decides to define doom-modeline-refresh-frame or not. But I think it should not impact the counsel-describe-function behaviors.
(with-no-warnings
(cond ((not (boundp 'after-focus-change-function))
(add-hook 'focus-in-hook #'doom-modeline-set-selected-window)
(add-hook 'focus-out-hook #'doom-modeline-unset-selected-window))
((defun doom-modeline-refresh-frame ()
(setq doom-modeline-current-window nil)
(cl-loop for frame in (frame-list)
if (eq (frame-focus-state frame) t)
return (setq doom-modeline-current-window (frame-selected-window frame)))
(force-mode-line-update))
(add-function :after after-focus-change-function #'doom-modeline-refresh-frame))))Can you describe steps of reproducing this? You're using emacs 26.1, and doom-modeline-refresh-frame should be not defined. If you enter doom-modeline-refresh-frame in counsel-describe-function, there should be no candidates.
The step is very simple. Move the cursor to doom-modeline-refresh-frame, and C-h f or M-x counsel-describe-function, then get this error.
I test this in Centaur Emacs and can't reproduce this. If the function is not define in emacs 26.1, when counsel-describe-function, the symbol should not be grabbed by emacs. Even inputing the symbol manually, I can not reproduce this.
Maybe you can try the master version, the elpa version has not been updated for serval months for unknown reasons.
OK. You mean melpa builds system doesn't work? I think you can file an issue on https://github.com/melpa/melpa. I encountered the similar issue a few months ago. They fixed and all run well now.
Update: I restart Emacs and no errors now. I don't know why the error occurred honestly. I am closing it now and keep testing. Thanks for the assistance!
Glad the issue is gone. Thanks for your information about melpa.
